Hi there,

I Have a large 6 Piece split mould for the main shell of a car body (1 Piece front end moulds and door moulds separate). Problem is that it doesn't have any wide flanges around the perimeter of the mould for the vacuum spiral or any sort of resin break. Instead of adding flanges could I envelop bag and run the vacuum spiral on the back side of the mould? Also by waxing the back of the mould I could run the peel ply around the edge on to the back side of the mould about 75mm to create a large enough resin break?  Or am I better to add wider flanges to the perimeter of the mould? Whatever I do I will be Envelop bagging. 

Thanks
